LED Street Lamp Base

Abstract

The present invention relates to a LED street lamp, which consists of power source box at front section, lamp holder at middle section and end cap at end section. The above mentioned lamp holder is composed of turnable framework, frame fixing unit connected with frame to limit frame rotation and several LED lighting modules installed side by side in the frame. A LED lighting module can be turned to connect with frame on which module positioning unit is set to limit the rotation of LED lighting module. For LED street lamp base of the invention, the major design part contains two bilateral symmetrical frames each of which is set with several LED lighting modules side by side. Both angles of frame and LED lighting module are adjustable of strong practicality, and so we can adjust them at any time according to practical street situation in order to ensure ideal street lighting brightness and evenness.

Description

FIELD OF THE INVENTION[0001]The present invention generally relates to street lighting, especially a framework to fix LED lighting module and a street lamp base of which the angle of LED lighting module can be adjustable.BACKGROUND OF THE INVENTION[0002]As the major application of semi-conductor lighting, LED street lamp features in long service life, strong mist penetration, and, more importantly, more energy saving than traditional street lamp.[0003]For the shortage of LED in optical performance, if you want to set LED light source on traditional lamp, it can only be done during the period of manufacture that is to carry out light distribution design according to the specific street lighting situation, namely to design lighting direction of each or each group of LED lamp, to light different street area and gain the overall lighting effect; the above mentioned street lamp can only be suitable for specific street lighting and each or each group of LED light towards fixed directions,...

AI Technical Summary

Benefits of technology

[0004]The invention provides a LED street lamp base that can adjust lighting angle according to street situation against the existing shortage.

[0012]As a preference, the up and down ends on periphery of clamp ring are set with sliding plates parallel to each other on which raised slide block is set; the internal side of left side plate is set with cavity to hold clamp ring while up and down ends of it are respectively set with 1 slide rail in which the slide block mentioned is set. Two parallel sliding plates are in touch with up and down ends of cavity to prevent clamp ring from circumferential turning, and slide block is set in slide rail to prevent clamp ring dropping from cavity.

[0014]As a preference, the LED lighting module mentioned above consists of radiator unit and heat conduction subplate of which top surface is to connect with radiator unit and bottom surface is set with print circuit and several LEDs. Circular ring and bulb are respectively set on left and right end faces of radiator unit. LED lighting module is an overall modeling including several LEDs forming a lighting tube that features in easy maintenance and replacement as well as good light concentration effect.

Problems solved by technology

For the shortage of LED in optical performance, if you want to set LED light source on traditional lamp, it can only be done during the period of manufacture that is to carry out light distribution design according to the specific street lighting situation, namely to design lighting direction of each or each group of LED lamp, to light different street area and gain the overall lighting effect; the above mentioned street lamp can only be suitable for specific street lighting and each or each group of LED light towards fixed directions, so the lighting angle cannot be adjusted to fit for other street lighting for certain limitations.
